Waves to Water - Ocean Waters

2019-2020


Our team, Ocean Waters, developed a wave-powered desalination system to provide drinking water in disaster relief and coastal locations as part of the US department of energy Waves to Water Prize. Our system can deliver about 1500L of fresh water over 5 days, fits within a standard 41x44x35in container, and can be easily deployed within a day.

It comprises of an onshore seawater Reverse Osmosis (RO) desalination unit coupled to a wave energy converter (WEC). The heave motion of the WEC is converted into high-speed rotary motion by the power take-off (PTO) module, powering a rotary vane pump. The pressurized water is sent onshore into a pressure-intensifying Energy Recovery Device (ERD) before being desalinated by the RO system.
